Took some better photos for comparison and have cut my hair the other day, grade 3 on top, 1 on sides. I prefer the way my hair looks slightly longer from the front but hate knowing that I have a big thin spot on the top
. Was meant to just trim the sides but got carried away and did it all. I think 3 is the lowest I will go for the moment, grade 1 is too short (unless it becomes required).
I uploaded this back in September, but thought I would use it as comparison as the hair is about the same length, around grade 3.
This is with flash, taken today.
This is without flash, taken today too.
I think there is minor improvement but sceptical. As I said before, it hasn't got worse so that's okay.
